Definitions
- the invention relates to a connection point between a coupling element and a line element connected to the coupling element and to a device for sealing the connection point (sealing device).
- the coupling element is, for example, a coupling element acting as a gas sampling point.
- Gas areas are to be separated spatially from electronic or electrical areas in accordance with applicable standards, among others in medical technology. This is especially true for medical care units. Such a rule is based on the fact that, for example, an increased oxygen concentration in conjunction with electrical potentials can lead to a fire or an explosion.
- a horizontal range foreclosure For the separation of a gas area of electronic or electrical areas, ie areas with electrical and / or electronic circuits or consumers, currently either a horizontal range foreclosure or a vertical range foreclosure is used.
- a horizontal range foreclosure use is made of the fact that escaping gas, for example oxygen (O 2 ), is heavier than the ambient air and sinks downwards in a foreclosed area under gravitational influence, where, for example, via a ventilation opening at the bottom of the unit Gas is carried out with the ambient air. Consequently, a region separated from an electronics or electrical area by a horizontal partition plate, which is arranged spatially below the electronics or electrical area, acts as a gas area.
- a vertical bulkhead separates the gas area from the electronics or electrical area, again Escaping gas, which is heavier than the ambient air, sinks in the foreclosed area under the influence of gravity down.
- the ISO11197 the particulate safety standard for medical supply units stipulates in the currently verified version (as of 2004) separation / containment and ventilation within the supply unit in order to counteract oxygen enrichment.
- the ISO11197, as of 2004, allows a nearly free positioning of gas sampling points for the removal of flammable gases, in particular O 2 and N 2 O.
- ISO11197, 2016 state in addition to the requirements of 2004, a defined leakage of 1 l O 2 per Minute for at least 10 min inflow time ago.
- An object of the present invention is to provide a way by which fire and / or explosion hazards due to escaping gas can be safely avoided, in particular to provide a way to avoid gas fire and / or explosion hazards essentially free to position can.
- this object is achieved by means of a gas-tight sealing device having the features of claim 1.
- a gas-tight sealing device having the features of claim 1.
- this on the one hand at least a portion of a coupling element or a portion of a wall with the coupling element and on the other hand, at least a portion of an including the coupling element connected line element, namely gas-tight encloses.
- the sealing device at a first sealing point gas-tight surrounds on all sides surrounding the conduit element and at a second sealing gas-tight all sides circumferentially to the coupling element or a wall, in or on which the coupling element is attached to. Between the first sealing point and the second sealing point, the sealing device encloses a volume determined by the geometry of the sealing device in a gastight manner.
- the coupling element is a device for forwarding an incoming gas stream into a line element which can be connected to the coupling element.
- a coupling element for example, a pipe connection in the form of a hose connector, wherein the conduit member is connected to a section for attaching one end of the conduit member functions.
- the conduit element is intended and arranged for forwarding the gas flow and the conduit element is, for example, a hose or the like.
- the advantage of the invention is that the sealing device with its volume between the first and the second sealing point possibly at the junction between the conduit element and the coupling element trapping gas traps and encloses gas-tight. A fire or explosion hazard due to escaping gas is thus safely avoided, because escaping gas can not reach the area of electrical or electronic circuits or consumers. Due to the achieved avoidance of the risk of fire and explosion, acting as a gas sampling coupling element can be basically arbitrarily positioned, so for example, in close proximity to electrical or electronic circuits or consumers.
- this is made in one piece from a material acting as a seal at the edge, for example an elastomer.
- a material acting as a seal at the edge for example an elastomer.
- this has a vent connection between the first sealing point and the second sealing point.
- the vent connection By means of the vent connection, it is possible to equalize the pressure between the interior of the sealing device and the surroundings, as well as to conduct gas trapped by means of the sealing device.
- a conduit member in the form of a hose or the like may be connected to discharge at a location of trapped gas this at a location where there is no risk of fire or explosion due to the gas.
- the sealing device in a particular embodiment of the sealing device this is geometrically and constructively designed in a manner that leads to a compact, only a small volume claiming design.
- the sealing device except for the coupling element or the part of the coupling element and the part of the line element includes no other components. Then, the conversions of the sealing device can be tightly connected to the outer surfaces of the coupling member and the duct member.
- Such a compact design means that a gas sampling point with a surrounding sealing device requires only slightly more space than a gas sampling point without such a sealing device. This facilitates the construction of devices, in particular medical devices, with at least one gas sampling point enclosed by a sealing device of the type described here and below.
- the innovation proposed here is also a medical device, in particular a medical device acting as a medical supply unit, with at least one coupling element and a line element connected to the coupling element, wherein at least a part of the coupling element and at least a portion of the line element by means of a sealing device here and hereinafter are included described type.

- This encloses gas-tight, for example, as a sampling point (gas sampling point) for combustible gas coupling element 12, in particular a coupling element 12 in the form of or in the manner of a Schlauchan gleichtülle, and a portion of an the coupling element 12 connected line member 14, so for example a portion of a hose.
- the sealing device 10 connects at a first sealing point 16 gastight peripherally circumferentially to the conduit member 14 and includes for example a seal which applies in a generally known manner in the region of the first sealing point 16 to the outer surface of the conduit member 14 and thus ensures a gastight seal.
- the sealing device 10 closes at a second sealing point 18 gas-tight all around either to the coupling element 12 or - as shown here - to a wall 20, for example a housing wall, a building wall or the like, namely a wall 20, in or on which the coupling element 12 is attached to.
- the sealing device 10 for the gastight connection comprises, for example, a seal which bears against the surface of the wall 20 in a manner known per se in the region of the second sealing point 18.
- a gas-tight connection of the sealing device 10 to the line element 14 or the coupling element 12 or the wall 20 can be effected by means of an adhesive bond.
- Such an adhesive bond has the advantage that it is directly effective for fixing the sealing device 10 in a fixed position as a whole.
- an additional mechanical fixation of the sealing device 10 may also be necessary, which holds it in position, ie in gas-tight contact with, for example, the wall 20.
- the sealing device 10 causes a gas-tight enclosure of the connection point between the conduit member 14 and the coupling element 12.
- the gas flowing out in the event of a leaky connection of the conduit member 14 to the coupling member 12 gas only into the interior of the sealing device 10. From there If desired, the gas may flow off over remaining gaps between the coupling element 12 and the wall 20, as shown in FIG FIG. 1 is shown by the outgoing from the connected to the coupling element 12 end of the line member 14 arrows.
- FIG. 2 shows an embodiment of the sealing device 10 according to FIG. 1 in which this has a venting connection for a below the differentiation of the line element 14 - but without waiving a broader generality - as a hose 22 designated discharge line element.
- Gas which in the case of a leaky connection of the line element 14 flows out to the coupling element 12 and first reaches the interior of the sealing device 10, can flow off via the hose 22.
- the venting connection and an optionally connected hose 22 function as venting of the sealing device 10.
- FIG. 3 shows an embodiment in which the sealing device 10 on the one hand connects to the conduit member 14 and on the other hand to the coupling member 12 and so ensures a gas-tight enclosure of the connection point between the conduit member 14 and the coupling element 12.
- the explanations related to FIG. 1 and FIG. 2 apply to the in FIG. 3 shown embodiment of the sealing device 10 accordingly, so that can be dispensed with unnecessary repetition.
- Unlike the embodiment in FIG. 1 and FIG. 2 closes the sealing device 10 at a second sealing point 18 in a gastight manner on all sides circumferentially to the coupling element 12 at.
- the representation in FIG. 4 shows an embodiment in which the sealing device 10 includes a plurality of connection points between a coupling element 12 and a respective conduit member 14 gas-tight.
- the sealing apparatus 10 has a number of first sealing points 16, corresponding to the number of line elements 14, at which the sealing device 10 adjoins the respective line element 14 in a gas-tight manner on all sides.
- this has a basically optional venting connection and via this venting connection, in a likewise basically optional manner, to the sealing device 10 is a hose 22 for the passage of leaked material at a connection point between the coupling element 12 and a line element 14 and by means of the sealing device 10 Connected gas connected.
- the sealing device 10 is preferably a one-piece plastic part.
- the sealing device 10 is elastic and made, for example, in one piece from a material acting as a seal at the edge, for example an elastomer.

Then the Sealing device 10 at the connection points between the items a seal or the like for a gas-tight connection of one of the items to the other item on.
- FIG. 2 and FIG. 3 may have a cylindrical basic shape, with a vertical axis parallel to a completely or partially enclosed in the sealing device 10 coupling element 12.
- the sealing device 10 may also have a polygonal basic shape, for example, a cube-shaped or cuboid basic shape.
- the outer shape of the sealing device 10 is arbitrary and can also - for example, with regard to the lowest possible volume and thus the smallest possible space - arbitrarily complex and, for example, the marginal lines of each housed, encapsulated in the interior of the sealing device 10 components (coupling element 12, line member 14) follow.
- the configurations according to FIG. 1 to FIG. 4 For example, they act as gas outlets. Due to the gas-tight enclosure of the or each basically leakage-prone connection point by means of the sealing device 10, the gas sampling point is enclosed in a gastight manner as a whole. In this way, the gas sampling point can basically be positioned at will and, for example, also be located in the vicinity of electrical or electronic circuits or consumers.
- Specified is a gas-tight sealing device 10, on the one hand at least part of a coupling element 12 or part of a wall 20 with the coupling element 12 and on the other hand, at least a portion of the The sealing device 10 at a first sealing point 16 gas tight all sides circumferentially connected to the line member 14, wherein the sealing device 10 at a second sealing point 18 gas tight all around the coupling element 12 or a wall 20, in or on the the coupling element 12 is attached, adjoining and wherein the sealing device 10 between the first sealing point 16 and the second sealing point 18 includes a gas-tight by the geometry of the sealing device 10 specific volume.

Description
Die Erfindung betrifft eine Anschlussstelle zwischen einem Kopplungselement und einem an das Kopplungselement angeschlossenen Leitungselement sowie eine Vorrichtung zum Abdichten der Verbindungsstelle (Abdichtungsvorrichtung). Bei dem Kopplungselement handelt es sich zum Beispiel um ein als Gasentnahmestelle fungierendes Kopplungselement.The invention relates to a connection point between a coupling element and a line element connected to the coupling element and to a device for sealing the connection point (sealing device). The coupling element is, for example, a coupling element acting as a gas sampling point.
Gasbereiche sind - unter anderem in der Medizintechnik - entsprechend geltender Normen räumlich von Elektronik- oder Elektrikbereichen zu trennen. Dies gilt speziell für medizinische Versorgungseinheiten. Eine solche Vorschrift basiert auf dem Umstand, dass zum Beispiel eine erhöhte Sauerstoffkonzentration in Verbindung mit elektrischen Potenzialen zu einem Brand oder einer Explosion führen können.Gas areas are to be separated spatially from electronic or electrical areas in accordance with applicable standards, among others in medical technology. This is especially true for medical care units. Such a rule is based on the fact that, for example, an increased oxygen concentration in conjunction with electrical potentials can lead to a fire or an explosion.
Zur Trennung eines Gasbereichs von Elektronik- oder Elektrikbereichen, also Bereichen mit elektrischen und/oder elektronischen Schaltungen oder Verbrauchern, wird aktuell entweder eine horizontale Bereichsabschottung oder eine vertikale Bereichsabschottung verwendet. Bei einer horizontalen Bereichsabschottung macht man sich zunutze, dass austretendes Gas, zum Beispiel Sauerstoff (O2), schwerer als die Umgebungsluft ist und in einem abgeschotteten Bereich unter Gravitationseinfluss nach unten sinkt, wo zum Beispiel über eine Ventilationsöffnung am Boden des Geräts eine Vermischung des Gases mit der Umgebungsluft erfolgt. Als Gasbereich fungiert folglich ein durch ein horizontales Schottblech von einem Elektronik- oder Elektrikbereich getrennter Bereich, der räumlich unterhalb des Elektronik- oder Elektrikbereichs angeordnet ist. Bei einer vertikalen Bereichsabschottung trennt ein vertikales Schottblech den Gasbereich vom Elektronik- oder Elektrikbereich, wobei auch hier austretendes Gas, das schwerer als die Umgebungsluft ist, in dem abgeschotteten Bereich unter Gravitationseinfluss nach unten sinkt.For the separation of a gas area of electronic or electrical areas, ie areas with electrical and / or electronic circuits or consumers, currently either a horizontal range foreclosure or a vertical range foreclosure is used. In a horizontal range foreclosure, use is made of the fact that escaping gas, for example oxygen (O 2 ), is heavier than the ambient air and sinks downwards in a foreclosed area under gravitational influence, where, for example, via a ventilation opening at the bottom of the unit Gas is carried out with the ambient air. Consequently, a region separated from an electronics or electrical area by a horizontal partition plate, which is arranged spatially below the electronics or electrical area, acts as a gas area. In a vertical range foreclosure, a vertical bulkhead separates the gas area from the electronics or electrical area, again Escaping gas, which is heavier than the ambient air, sinks in the foreclosed area under the influence of gravity down.
Aktuell ist eine solche Trennung durch Ventilationsöffnungen, Schottbleche oder komplett getrennte Kanäle realisiert. Die ISO11197, der partikuläre Sicherheitsstandard für medizinische Versorgungseinheiten, schreibt in der aktuell verifizierten Version (Stand 2004) eine Trennung/Schottung sowie eine Ventilation innerhalb der Versorgungseinheit vor, um einer Sauerstoffanreicherung entgegenzuwirken. Die ISO11197, Stand 2004 erlaubt eine nahezu freie Positionierung von Gasentnahmestellen zur Entnahme brennbarer Gase, insbesondere O2 und N2O. Allerdings schreibt die ISO11197, Stand 2016 zusätzlich zu den Anforderungen gemäß dem Stand aus 2004 eine definierte Leckage von 1 l O2 pro Minute für mindestens 10 min Einströmzeit vor. Hierdurch wird die freie Positionierung von Gasentnahmestellen zur Entnahme brennbarer Gase stark eingeschränkt, denn durch die Definition der Leckagegröße ist die Positionierung einer Gasentnahmestelle zum Beispiel über einer Steckdose nicht mehr möglich. Das große O2-Volumen sorgt für einen ansteigenden O2-Wert über einen kritischen Wert von zum Beispiel 25 Vol.-%. Zulässige Positionierungen sind dann nur noch eingeschränkt möglich. Zum Beispiel durch vertikale Bereichsabschottungen und vertikale Positionierung (Gas neben Elektro) oder horizontale Bereichsabschottung und horizontale Positionierung (Elektro über Gas).Currently, such a separation is realized by ventilation openings, bulkhead plates or completely separate channels. The ISO11197, the particulate safety standard for medical supply units, stipulates in the currently verified version (as of 2004) separation / containment and ventilation within the supply unit in order to counteract oxygen enrichment. The ISO11197, as of 2004, allows a nearly free positioning of gas sampling points for the removal of flammable gases, in particular O 2 and N 2 O. However, ISO11197, 2016 state, in addition to the requirements of 2004, a defined leakage of 1 l O 2 per Minute for at least 10 min inflow time ago. As a result, the free positioning of gas sampling points for the removal of combustible gases is severely limited, because the definition of the leak size, the positioning of a gas sampling point, for example, via a power outlet is no longer possible. The large O 2 volume provides a rising O 2 value above a critical level of, for example, 25% by volume. Permitted positioning is then only possible to a limited extent. For example, by vertical range foreclosures and vertical positioning (gas next to electric) or horizontal range foreclosure and horizontal positioning (electric via gas).
Eine Aufgabe der vorliegenden Erfindung besteht darin, eine Möglichkeit anzugeben, mittels derer Brand- und/oder Explosionsgefahren aufgrund von ausströmenden Gas sicher vermeidbar sind, insbesondere darin, eine Möglichkeit anzugeben, bei Vermeidung von Brand- und/oder Explosionsgefahren Gasentnahmestellen im Wesentlichen frei positionieren zu können.An object of the present invention is to provide a way by which fire and / or explosion hazards due to escaping gas can be safely avoided, in particular to provide a way to avoid gas fire and / or explosion hazards essentially free to position can.
Erfindungsgemäß wird diese Aufgabe mittels einer gasdichten Abdichtungsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Dazu ist bei einer solchen Abdichtungsvorrichtung vorgesehen, dass diese einerseits zumindest einen Teil eines Kopplungselements oder einen Teil einer Wandung mit dem Kopplungselement sowie andererseits zumindest einen Abschnitt eines an das Kopplungselement angeschlossenen Leitungselements einschließt, nämlich gasdicht einschließt. Für diesen gasdichten Einschluss schließt die Abdichtungsvorrichtung an einer ersten Abdichtstelle gasdicht allseitig umlaufend an das Leitungselement an und an einer zweiten Abdichtstelle gasdicht allseitig umlaufend an das Kopplungselement oder eine Wandung, in oder an der das Kopplungselement angebracht ist, an. Zwischen der ersten Abdichtstelle und der zweiten Abdichtstelle schließt die Abdichtungsvorrichtung ein durch die Geometrie der Abdichtungsvorrichtung bestimmtes Volumen gasdicht ein.According to the invention, this object is achieved by means of a gas-tight sealing device having the features of claim 1. For this purpose, it is provided in such a sealing device that this on the one hand at least a portion of a coupling element or a portion of a wall with the coupling element and on the other hand, at least a portion of an including the coupling element connected line element, namely gas-tight encloses. For this gas-tight enclosure, the sealing device at a first sealing point gas-tight surrounds on all sides surrounding the conduit element and at a second sealing gas-tight all sides circumferentially to the coupling element or a wall, in or on which the coupling element is attached to. Between the first sealing point and the second sealing point, the sealing device encloses a volume determined by the geometry of the sealing device in a gastight manner.
Bei dem Kopplungselement handelt es sich um eine Vorrichtung zur Weiterleitung eines ankommenden Gasstroms in ein an das Kopplungselement anschließbares Leitungselement. Als Kopplungselement fungiert zum Beispiel eine Rohrverbindung in Form einer Schlauchanschlusstülle, wobei das Leitungselement an einen zum Aufstecken eines Endes des Leitungselements bestimmten Abschnitt angeschlossen wird. Das Leitungselement ist zur Weiterleitung des Gasstroms bestimmt und eingerichtet und bei dem Leitungselement handelt es sich zum Beispiel um einen Schlauch oder dergleichen.The coupling element is a device for forwarding an incoming gas stream into a line element which can be connected to the coupling element. As a coupling element, for example, a pipe connection in the form of a hose connector, wherein the conduit member is connected to a section for attaching one end of the conduit member functions. The conduit element is intended and arranged for forwarding the gas flow and the conduit element is, for example, a hose or the like.
Der Vorteil der Erfindung besteht darin, dass die Abdichtungsvorrichtung mit ihrem Volumen zwischen der ersten und der zweiten Abdichtstelle eventuell an der Verbindungsstelle zwischen dem Leitungselement und dem Kupplungselement ausströmendes Gas auffängt und gasdicht einschließt. Eine Brand- oder Explosionsgefahr aufgrund von ausströmendem Gas ist damit sicher vermieden, denn ausströmendes Gas kann nicht in den Bereich elektrischer oder elektronischer Schaltungen oder Verbraucher gelangen. Aufgrund der erreichten Vermeidung der Brand-und Explosionsgefahr kann ein als Gasentnahmestelle fungierendes Kopplungselement im Grunde beliebig positioniert werden, also zum Beispiel auch in räumlicher Nähe zu elektrischen oder elektronischen Schaltungen oder Verbrauchern. Dies erleichtert die Konstruktion von Geräten, zum Beispiel Medizingeräten, insbesondere Medizingeräten in Form von medizinischen Versorgungseinheiten, welche zumindest eine Gasentnahmestelle umfassen, und erlaubt zum Beispiel eine kompaktere Bauform, weil kein besonderer Abstand zwischen einer Gasentnahmestelle und elektrischen oder elektronischen Schaltungen oder Verbrauchern eingehalten werden muss.The advantage of the invention is that the sealing device with its volume between the first and the second sealing point possibly at the junction between the conduit element and the coupling element trapping gas traps and encloses gas-tight. A fire or explosion hazard due to escaping gas is thus safely avoided, because escaping gas can not reach the area of electrical or electronic circuits or consumers. Due to the achieved avoidance of the risk of fire and explosion, acting as a gas sampling coupling element can be basically arbitrarily positioned, so for example, in close proximity to electrical or electronic circuits or consumers. This facilitates the construction of devices, for example medical devices, in particular medical devices in the form of medical supply units, which comprise at least one gas sampling point, and allows for example a more compact design, because no special distance between a gas sampling point and electrical or electronic circuits or consumers must be respected.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche. Dabei verwendete Rückbeziehungen weisen auf die weitere Ausbildung des Gegenstandes des Hauptanspruches durch die Merkmale des jeweiligen Unteranspruches hin und sind nicht als ein Verzicht auf die Erzielung eines selbständigen, gegenständlichen Schutzes für die Merkmalskombinationen der rückbezogenen Unteransprüche zu verstehen. Des Weiteren ist im Hinblick auf eine Auslegung der Ansprüche sowie der Beschreibung bei einer näheren Konkretisierung eines Merkmals in einem nachgeordneten Anspruch davon auszugehen, dass eine derartige Beschränkung in den jeweils vorangehenden Ansprüchen sowie einer allgemeineren Ausführungsform des gegenständlichen Einschraubverbinders nicht vorhanden ist. Jede Bezugnahme in der Beschreibung auf Aspekte nachgeordneter Ansprüche ist demnach auch ohne speziellen Hinweis ausdrücklich als Beschreibung optionaler Merkmale zu lesen.Advantageous embodiments of the invention are the subject of the dependent claims. This used backlinks point to the further development of the subject matter of the main claim by the features of the respective subclaim and are not to be understood as a waiver of the achievement of an independent, objective protection for the feature combinations of the related subclaims. Furthermore, with regard to an interpretation of the claims and the description in a closer specification of a feature in a subordinate claim, it is to be understood that such a restriction in the respective preceding claims as well as a more general embodiment of the subject screw-in connector does not exist. Each reference in the description to aspects of subordinate claims is therefore to be read even without special reference expressly as a description of optional features.
Bei einer Ausführungsform der Abdichtungsvorrichtung ist diese einstückig aus einem randseitig als Dichtung fungierenden Material, zum Beispiel einem Elastomer, hergestellt. Die resultierende Flexibilität der Abdichtungsvorrichtung erleichtert deren Handhabung und Anbringung. Die Einstückigkeit vermeidet die Verwendung einer ansonsten notwendigen Dichtung und erleichtert damit ebenfalls die Handhabung und Anbringung.In one embodiment of the sealing device, this is made in one piece from a material acting as a seal at the edge, for example an elastomer. The resulting flexibility of the sealing device facilitates its handling and mounting. The one-piece design avoids the use of an otherwise necessary seal and thus also facilitates handling and attachment.
Bei einer weiteren Ausführungsform der Abdichtungsvorrichtung weist diese einen Entlüftungsanschluss zwischen der ersten Abdichtstelle und der zweiten Abdichtstelle auf. Über den Entlüftungsanschluss ist ein Druckausgleich zwischen dem Innern der Abdichtungsvorrichtung und der Umgebung sowie eine Fortleitung von mittels der Abdichtungsvorrichtung aufgefangenem Gas möglich. An den Entlüftungsanschluss kann ein Leitungselement in Form eines Schlauchs oder dergleichen angeschlossen sein, um bei einer Fortleitung von aufgefangenem Gas dieses an einem Ort abzulassen, an dem aufgrund des Gases keine Brand- oder Explosionsgefahr besteht.In a further embodiment of the sealing device, this has a vent connection between the first sealing point and the second sealing point. By means of the vent connection, it is possible to equalize the pressure between the interior of the sealing device and the surroundings, as well as to conduct gas trapped by means of the sealing device. At the vent port, a conduit member in the form of a hose or the like may be connected to discharge at a location of trapped gas this at a location where there is no risk of fire or explosion due to the gas.
Bei einer besonderen Ausführungsform der Abdichtungsvorrichtung ist diese geometrisch und konstruktiv in einer Art und Weise gestaltet, die zu einer kompakten, nur ein geringes Volumen beanspruchenden Bauform führt. Dazu ist vorgesehen, dass die Abdichtungsvorrichtung außer dem Kopplungselement oder dem Teil des Kopplungselements sowie dem Teil des Leitungselements keine weiteren Komponenten einschließt. Dann können die Wandlungen der Abdichtungsvorrichtung eng an die Außenoberflächen des Kopplungselements und des Leitungselements anschließen. Eine solche kompakte Bauform führt dazu, dass eine Gasentnahmestelle mit einer umgebenden Abdichtungsvorrichtung nur unwesentlich mehr Bauraum beansprucht als eine Gasentnahmestelle ohne eine solche Abdichtungsvorrichtung. Dies erleichtert die Konstruktion von Geräten, insbesondere Medizingeräten, mit zumindest einer mittels einer Abdichtungsvorrichtung der hier und im Folgenden beschriebenen Art eingehausten Gasentnahmestelle.In a particular embodiment of the sealing device this is geometrically and constructively designed in a manner that leads to a compact, only a small volume claiming design. For this purpose, it is provided that the sealing device except for the coupling element or the part of the coupling element and the part of the line element includes no other components. Then, the conversions of the sealing device can be tightly connected to the outer surfaces of the coupling member and the duct member. Such a compact design means that a gas sampling point with a surrounding sealing device requires only slightly more space than a gas sampling point without such a sealing device. This facilitates the construction of devices, in particular medical devices, with at least one gas sampling point enclosed by a sealing device of the type described here and below.
Insgesamt ist die hier vorgeschlagene Neuerung auch ein Medizingerät, insbesondere ein als medizinische Versorgungseinheit fungierendes Medizingerät, mit zumindest einem Kopplungselement und einem an das Kopplungselement angeschlossenen Leitungselement, wobei zumindest ein Teil des Kopplungselements sowie zumindest ein Abschnitt des Leitungselements mittels einer Abdichtungsvorrichtung der hier und im Folgenden beschriebenen Art eingeschlossen sind.Overall, the innovation proposed here is also a medical device, in particular a medical device acting as a medical supply unit, with at least one coupling element and a line element connected to the coupling element, wherein at least a part of the coupling element and at least a portion of the line element by means of a sealing device here and hereinafter are included described type.
